Thisingnut 50 mounted on the stud 48 serves to 110 hold the rod againstmovement and consequently hold the delivery board 38 and the deflectorboard 4&1 in their adjusted positions.

In order to control the current of air passing into the chute 30, thechute 34 has pivotally mounted therein as shown at 51, a plurality ofshutters 52. These shutters are connected by means of arms 53 with anoperating rod 54. This rod passes through an opening 55 provided in thehousing and carries at its outer end a handle 56. By moving the rodlongitudinally, the shutters may be simultaneously adjusted to regulatethe passage 34.

The outlet passage is provided with an opening 57 which is covered by ascreen 58, to provide communication with a trough 59 within whichoperates a spiral conveyor 60. Any grain which may be blown upward pastthe deilector screen 41, will fall upon the screen 58 and will gravitatebackward into the conveyor 32. Any small heavy particles of foreignmatter will pass through this screen and be carried outward by means ofthe conveyor 60. Hooks 61 may be provided at the end of the chute 59 toprovide supporting means for a bag.

A brush 62 is mounted in the top of the housing upon a rod or bar 63.This brush is inclined in conformity with the taper of the drum and theends of the rod or bar 63 are adjustably mounted in the housing as shownat 64, so that the brush may be adjusted with respect tothe drum to keepthe periphery of the latter clean for the passage of the'grain.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and .the right is herein reserved tomake such Changes as properly fall within the scope of the appendedclaim.

Having described the invention what is claimed is:-

'In a grain separator, a cylindrical housing, Yan articulated drumrotatably supported within the housing and having opposite open ends,spiders journaled in the ends of the housing and rotatably supportingsaid drum at opposite open ends thereof, a feed chute communicatingcentrally with the housing and said drum, a trough extendingvlongitudinally within the drum, communicating with said feed chute andhaving a longitudinalV slot in its bottom, a conveyor spiral operatingin said chute and trough, the drum being tapered in the direction of thefeed chute, spirally arranged agitators secured within the drum, adischarge spout leading from one end of the housing, a verticallydisposed reduced portion depending from the housing at its lowermostpoint and forming a grain passage, a vertically swinging adjustabledelivery board arranged within the reduced portion of the housing, avertically swinging defiector board in the reduced portion of thehousing above the delivery board, a link connecting the deflector boardand delivery board together whereby simultaneous adjustment thereof maybe had, a screen fitted in the delivery board and disposed outside ofthe reduced portion of the housing, and a'blower housing related withthe reduced portion of the housing and having its air discharge inconfronting relation to the screen whereby the blown air from the blowerhousing will pass through the screen to be active upon grain agitated bythe deiiector board for separating chan and other light foreignparticles from the grain upon the latter reaching the delivery board.
